VESSEL FIRE-EXTINGUISHING APPARATUS.

Specification of Letters Patent No. 32,389, dated May 21, 1861.

To all whomtt may concern:

Be it known that I, JAMES L. STUART, of New York, in the county andState of New York, have invented, made, and applied to use a new andImproved Apparat-us for the Extinguishment of Fires on Shipboard, whichI terni the Hydraulic Safety Machinery; and I do declare the followingto be a full, clear, and correct description thereof, reference beinghad tothe accom panying drawings, and to the letters of reference markedthereon, in which- Figure l is a side view, showing outA side of vessel.Fig.` 2, a longitudinal vertical section of the same. Fig. 3, a top viewof the same, one half, showing portions of the top of the rectangulartube Are moved. Fig. 4, a side elevation ofthe cast iron frame Gl Fig.5, a sectional view of the same. (Fig- 6, a top view of the same,showing openings forthe slides N N. Fig. 7, a cross section of the same.Fig. 8, a view of one of the valves placed in the side of the tube Aforward of the pump H, to be used in case of a leak.

Fig. 12, a horizontal section of the same.

In the drawings, like parts of the invention are indicated by the sameletters of reference. o

The natureof my invention consists in the construction and operation ofa new and novel apparatus to be usedA in connection with the means ofpropulsion for the eX- tinguishment of lires on shipboard.

To enable those skilled in the arts to make and use my invention I willspeak of the construction and operation of the saine.

In connection `with my improved safety apparatus I employ (l) a new andnovel means of propulsion; (2) a new and novel means for the dischargeof water, in the case of a serious leak; (3) a new and novel mode ofsteering.

N N show two slides of iron, inclosed in the frame G and working in thesame, the frame G being grooved as at O, Fig. 7, for this purpose. Theseslides N N are grooved at their bottom edge and are provided withrubber-packing to prevent the water from entering the main pipe A, whenthe slides N N are depressed or closed. `These slides R R show twotubular masts provided i with flanges S S, to secure them to the mastpedestals lV V resting uponthe tube A. These pedestals IV W contain eachtwo valves as at X X', opening upward for the admission of water intothe tubular masts R R, said valves X X being closed by depressing therods Y and Y, whileby elevating these rods Y and Y the valves are openedand the water allowed to enter the tubular masts R R.

The masts R R may be provided at the bottom with stop-cocks to allow thewater to escape therefrom, into the hold of the vessel, whence it may bepumped out, the rotary pump H being provided with stop-cocks p p forthis purpose.

T T show pipes connected with the tubular masts R, R, and provided withhydrants t, to which may be attached hose, (V) while by means of thestop-cocks u, u', u2, ug, water may be shut off from either one side orthe other of the vessel. Similar slides to those shown at N N are placedin the bows of the vessel and may be arranged and operated in the samemanner or in an equivalent way. Y

Operation: In case of fire, the hose is attached to any of the hydrants(t) desired. If the ship be propelling bows first, the rod Y is raisedthe valves as at open by the pressure of theA water below and the waterrushes up the tubularmast R, from the fact that the branch tubes B B aresmaller aft than forward. In case the quantity of water thus supplied benot suthcient, it may be increased by depressing the slides N Npreviously described. The water thus forced into the tubular mast Rpasses through the pipes T T to the hydrants t, and is thrown upon thefire by means of hose V as previously described. After the lire has beenextinguished, the rod Y is depressed, thereby closing the valves as atX, the stop-cock at the bottom of the mast R is opened and the waterflows from the mast pedestal IV into the hold, whence it is pumped outas previously stated. In case the vessel be propelling stern first, therod Y is raised, slides similar to N N are depressed, thus introducingthe water into the tubular mast R and the operation just described isgone through with.

It will be observed that each of the tubular masts is provided with athrottle valve a2, which, in case of lire occurring in the rigging or inthe vicinity of the masts, may be opened and allow the water to beforced out of the mast head and when desired the valves a2 may be openedand the water be v elevated to the mast head as a means of testing thestrength of the tube A.

In Fig. 11, the apparatus for the extinguishment of lire on shipboard,is shown used in connection with the present mode of propelling, inwhich case I employ the rectangular tube A, the rotary pump H, theslides N2 N3 placed on each side of the pump H, .the throttle valves a4a? opening communication between the tube A and the tubes B3 B3 ofy thetire department; also the valves 10 and 11 placed as shown in Fig. 2.Levers marked 4:0 are used to operate the throttle valves at a4, and 41shows a wheel on the side wheel or propeller shaft 4Q gearing into theshaft L and operating the rotary pump the shaft L and operating therotary pump H.

Operation: In case of a lire and the driving wheel I moving in thedirection of the arrow, the slide N3 and the throttle valve a4 areopened, the latter by means of the lever 40. The water rushes throughthe tube A as shown by the arrows and up the tube B3, and thence passesthrough the pipes T T to the hydrants t, to which is attached hose V andis thrown upon the fire as previously described. If the wheel I berunning in the opposite direction, the slide N2 and throttle valve a*are opened and the water ascends the tube B3 and the operationpreviously described is repeated. IVhen the lire has been extinguishedand the hose v having been removed, air is admitted through the opened Yhydrants t, the throttle valve a4 and the slide N3 being opened, thewater is discharged by means of the tube A through an aperture in theside or bottom of the vessel.

I do not of course desire in the employment of my invention to limitmyself to the eXact arrangement of parts as shown.

Having thus described my invention what I claim therein as newand desireto secure by Letters Patent is- The combination of the rotary pump H,slides N N tubular masts R and R, valves X and X and pipes T and Tprovided with hydrants t, when combined and operated as shown and forthe purpose set forth.
